Letters Patent No. 92,370, daad .my c, 1869.

IMPROVEMENT IN PICKS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whoml it may concern:

Be it known that I, NATHAN ROSE, of Belmont, in the county of Allegany, and State of New York, have. invented certain new and useful Improvements in Picks; and I do hereby declare that the following is a full, clear,`and exact description thereof, reference 4being had t0 the. accompanyingdrawings, and to the letters of reference marked thereon, which form a part ofthis specification, andin which- Figure l represents a perspective of the holder;

Figure 2, a perspective, with the pick removed;

Figure 3, a perspective, with the clamp opened;

Figure 4,'a perspective, showing one side of the holder;

Figure 5, aperspective, showing the other side of the holder;

Figure, a perspective'of the clamp; and

Figure 7, a perspectiveof the holder, with the pick and clamp removed.

Similar letters indicate like parts in all the gures.

My invention relates to improvements in pickholders, and to this end v It consists in the method vof adjusting and supporting the end of the pick in the holder, so that every blow upon the piek tightens the same in the holder; all of which will hereinafter be fully set forth.

To enable others skilled in the art to which my invention appertainsto make and use the same, I will now describe its construction and operation. y

In the accompanying drawingsvas seen, in tig. 1.

A representsthe holder, made in the shapeof a wedge; f

b b represent a mortise, cut in each opposite face of the holder; and

b', a mortise cut in the centre of the holder, connecting the two mortises ,b bl

. D represents the clamp, made as seen in iig. 6, and. l pivoted in the mortise b', and working upon the prin-v ciple of a pair of tongs.

E is the pick, inserted in the blunt end ofthe holder,

By this arrangement any sized pick can be used with the holder described; and, also, the more the pick is used the. firmer it is held in theholder.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, isi 1f The holder A, constructed as described, and provided -with the hinged clamp D, substantially in the manner and for thc purpose described.

2. A pick-holder, consisting'of the holder A, provided with mortises b b b' and pick E, all constructed,

arranged, and operating substantially in the manner Y and for the purpose specified.

In testimony that I claim the foregoing as my own, I afiix mysignature, in presence of two witnesses. NATHAN ROSE.
